CHANGE-GIVING VENDER.

Specification of Letters Patent.

Patented Feb. 16, 1915.

' Application filed October 22, 1913. Seria1No. 796,558.

To all whom it may concern Be it known that I, ARTHUR E. H. BAmLI,

a subject of the King of Italy, residing in Pittsburgh, county of Allegheny, State of Pennsylvania, have invented certain new and useful Improvements in Change-Giving Vendors, of which the following is a specification. I

My invention provides a change-giving appliance for mechanical vendors which will widen their field of use by enabling them either to receive the price coin and deliver the purchase, or to receive a coin of higher value and deliver the purchase and the change.

The drawings illustrate a machine selling articles for one cent and adapted to receive cents, and deliver purchases, or to receive five cent coins and deliver purchases and four cents change. But it is obvious that the price-coin might be five cents or a quarter and the larger receivable coin a quarter, or

a dollar; or that the price coin might be of one value, the change coin of another and the large coin of a third.

In general terms, my change-giving ap-- pliance comprises acase, either part of or adapted to be connected with the vender case and having on one face a coin-slot, a slide-knob and a change-pan; and contained therein an operable, preferably a lever-andlink connection with the vendor. mechanism; a change-coin hopper and change-giving mechanism; a coin-switch adapted to divert purchase-coins to the change-pan when the vender mechanism is unworkable; a manually-operable slide operably related with the coin-slot, the change-giver, the vendor-lever, and the coin-switch; and a slot-gage adapted, when changecannot be given, to narrow the coin-slot to fit price-coins and exclude large ones.

In the drawings, Figure 1 is a vertical axial section, Fig. 9. a lateral section on the line 22 of Fig. '1, with the coin-slot in ele' vation. Figs. 3 and 1 are sectional plans respectively on the lines 3-3 and 41 of Figs. 1 and 2, Fig. 5 an enlarged axial section through the outlet of the change-hopper,- Fig. 6 an elevation of the upper part of the slot-gage plate,and Fig. 7. a detail of the switch mountingz The case 1 is a closed prism made of sheet metal by known modes. In the upper part.

of its face is a coin-slot 1? adapted 101113116 large coin and adjacent thereto a sign-slot.

1 through which to read a sign Cents (or the price-coin) only, which automatically reglsters with and is read through the sign slot when the machine cannot give change. Projecting from the lower part of the face is a change-pan 1 communicating through an opening 1 with the interior of the case; and between it and the slots a Inside the case are fixed slide-ferrule 1". parts as follows: the slide-way 1 and thereon a spring-socket 1 a fulcrum post 1 for the vendor lever 4, anda suitably mounted magnet 1; the coin-chute 1, which is a channeled plate with a somewhat shorter cover plate 1 both let into the face plate and having marginal slots adjacent thereto for the slot-gage; a change hopper 1 a change gage block 1 which contains an opening in which the end of the hopper is steadied and which also formsa change-coinpassage 1; a coin-sorter 1 formed with two pairs of rabbets or guides respectively l for price-coins, which they divert into the hopper and the other 1 for large coins, go

which they deflect into a suitable bin; a switch chute, 1 to convey rejected coinsto the change-pan; a partition 1 which in closes the lower part of the'change-giver; a fulcrum post 1; a sway brace 1 to steady 35 the hopper 1 and a guide-plate 1 for the slot-gage. i

The slot-gage 2' is a slotted plate formed with a price-coin'gage 2 the width of the price-coin and a sign 2 Cents only), is 9:}

suspended by a gage spring 2 and its lower end rests on oneend of a lever 2 fulcrumed on the change block 1 and whose other end is formed into a finger 2*, which plays beneath ,or into the hopper 1". The weightfiS of the'number of change coins ;C due for once giving change, extrudes the finger 2 from the hopper 1 rocks the lever 2? and lifts the gage 2 so that its sign 2 is concealed and its wide slot envelops the change slot 1 and large coins can be received;

but if there be fewer change coins in the hopper, the unsupported weight of the gage 2 depresses the lever 2 lifts such coins, and

descends so that its price-coin slot 2 so narrows the coin-slot 1 that price-coins only can be received and the sign 2* registers with and can be read through the sign slot 1. V The slide is in two parts, namely, the

motive slide 3 and the driven slide 3 the latter operative only when and by means a fixed pin 11 anda wiper arm 35.

of a' coin located between said slides. The

motive slide 3 comprises a plate 30 mountedin the slideway adjacent to the face-wall of the case, terminating inwardly in a' V- shaped socket with'beveled lower edges 31, and fast to-a stem 32 which extends through the ferrule 1 terminates in a knob 33 and has a shoulder between which and the case a retracting spring. 34 is strained. A bellcrank wiper, centrally pivoted in the plate 32, has a slotted arm 36 whose slot engagessaid arm; and on thereturn stroke the bell If an iron disk or washer be fed into the machine, the magnet l attracts and lifts it into the path of the wiper arm 35 and when the motive slide is advanced the engagement of the wiper slot with the pin 11 causes the wiper arm 35 to wipe the iron 0d the magnet so that it will fall into the general bin and not cause the machine to delivereither goods or coins. The vender lever 4 is a bell. crank pivoted on the post 1 has an arm 41 which extends over the driven slide 3 and a slotted arm 42 operably connected, through a link 43 with the vender mechanism, to operate it whenthe.

driven slide-is moved by means of a coin.

The driven slide 3 comprises a plate 3 mounted in theslide-way 1, and the same plane with the motive slide, terminating inwardly in a V-socket like that of the motive slide and with similarly beveled edges 3, terminating outwardly in an offset abutment head 3 which plays in the socket 1 .and

strains a feed spring 3 therein, contains a.

.slot 3 for the change lever 60 and, by means of suitable forks 3 pivotally mounts a compound lever comprised of a slotted primary lever 3 and a secondary bell-crank 3', both fulcrumed on thesame pin. The lever 3 contains a slot 3 and is upheld by a spring 3 in initial strain suiiicient to cause the operation of the vender mechanism under normal conditions. One arm of the bell-crank 3 operates the vender lever 4, and its other arm is normally strained against the priput in the coin-slot 1 descends the chute and falls on the switch plate, line with and between the slides 3 and 3. The motive slide 3 is then. pushed in, contacts with the 'coin, and shoves it against the driven slide,

which is thus pushed back and brings the vertical arm of the bell-crank 3 against the vender lever 4; and if the vending mechanism works properly swings said lever andoperates said mechanism. The other.-

6 arm of the bell-crank presses on and tends to depress the primary lever 3 which, up-

held by the spring 3, holds the switch plate horizontal unless thevending mechanism is out of order; in which case the increased resistance of the vender lever 4 causes the bell crank to compress the spring 3 and depress the primary lever 3, whose slot 3 c'oacting with the switch crank 51, tips the switch plate 5 and dumps the coin into the switch-chute 1*. The stroke of the arm 41 of the lever 4 is less than that of the driven slide and bell-crank 3", which therefore passes crank is swung by contactwith said arm and latched therewith by the spring 3.

1 The change mechanism 6 comprises a lever 60 pivoted on the post 1", extending its short end through the slot 3 of the driven whose wide posterior part 6 permits .the descent of changecoins when the knife is advanced; and in the upper face, about the end of the hopper 1 and over the interior narrow portion 6 of the broom shaped slot, a hole 6 whose posterior margin is a knife 6 whose. distance from the bottom flanges 6 equals the aggregate thickness of the numbers of change coins to be given as change and which when the gage is advanced, separates the right number of coins from those in the hopper. When the gage is advanced, the knife 6 retains inthe hopper all the change coins not separated for change; and

' when it is retracted, the coins descend and rest upon and are retained in the hopper by the gage flanges 6. Therefore only the due number of coins can be given as change. lVhen a price coin is slipped into the coin slot 1 it descends the chute 1 and falls on the switch plate5; and the motive slide 3 is pushed in.

As shown in Fig. 1, the thickness of a price-coin is less than that of the slide plates 30 and 3", its diameter is less than their opening and its play between them is increased by the bevels of their edges, 31 and 3; and this play is so great that when the motive slide. 3 is fully advanced the driven slide 3 does not operate the change lever 60 and mechanism 6. Pushing in the slides operates the vender lever 4 if the machine. is in working order; and if not the switch plate 5 is tipped and the coin dumped into the switch chute 1 and change pan 1, as above described.

If the vender lever can be swung, the motive slide 3 shoves the coin off the switch from said motive slide and to cause the opplate/ and it fallsupon the inward rabbets 7 1 of the sorter 1 The machine illustrated it and the slide plates are of substantially equal thickness and their opening is as nearly as may be equal to its diameter, so that it has no unnecessary play between them; and when the motive-slide 3 is pushed in, the large coin (if it be not switched to the change-pan) moves the driven slide its full stroke, it swings the change lever 60 and advances the change gage 6*, whose knife, 6 separates from the change-coin in the hopper the number due for change while the wide end 6 of its slot permits them to fall into the change 'pan. The large coin falls on and slides down the outer rabbets 1'- vanced to said delivery, a manually-open able motive slide, a driven slide adapted to be operated, by means of an interposed coin,
